Question 990
A peer reviewer inspects Network path test to DNS servers after it was introduced to separate name-resolution failure from inaccessible directory servers after a host image update. Which result should be documented?
Explanation
Correct Answer
This is the direct functional outcome for Network path test to DNS servers: direct DNS lookup fails even though approved IP connectivity to the server succeeds. DNS tests distinguish resolution failures from transport reachability. The observed behavior supports the specified acceptance requirement.
Incorrect Answers
That evidence concerns NSG effective security rules check, used to identify a higher priority deny rule overriding a proposed allow rule for storage access. It does not establish whether Network path test to DNS servers satisfies the current requirement to separate name-resolution failure from inaccessible directory servers after a host image update.
That evidence concerns AVD connection diagnostics for handshake errors, used to find the failed service-side connection stage when a user never reaches a session host. It does not establish whether Network path test to DNS servers satisfies the current requirement to separate name-resolution failure from inaccessible directory servers after a host image update.
That evidence concerns Azure Firewall diagnostic deny logs, used to locate a firewall policy that silently blocks an AVD control-plane destination. It does not establish whether Network path test to DNS servers satisfies the current requirement to separate name-resolution failure from inaccessible directory servers after a host image update.
